OC-48 DWDM SFP 40km Transceiver Description
Our EDGEOPTIC DWDM-2.67G-SFP-40 is a multi-vendor compatible OC-48/STM-16 DWDM SFP optical module designed for high-density high-speed wavelength division multiplexing applications operating over single-mode fiber infrastructure. This DWDM transceiver enables maximum spectral efficiency by utilizing tightly spaced wavelength channels according to ITU-T G.694.1 grid specifications, making it an essential building block for carrier-class transport networks, data center interconnects, and enterprise deployments requiring the highest possible channel density combined with multi-rate operational flexibility over existing fiber infrastructure.
The DWDM-2.67G-SFP-40 module is available across 45 DWDM wavelength channels (ITU channels 17-61) within the C-band spectrum, utilizing 100GHz channel spacing for precise wavelength allocation. Each module supports multi-rate operation from 100 Mbps to 2.67 Gbps, enabling Gigabit Ethernet, 1G and 2G Fiber Channel, SDH/SONET standards including STM-1, STM-4, and STM-16, as well as OTN applications including ODU0, ODU1, and OTU1. When combined with passive or active DWDM multiplexers, operators can aggregate up to 45 independent wavelength channels over a single fiber pair – more than double the capacity of CWDM systems – dramatically increasing link capacity for bandwidth-intensive applications. Our OC-48 DWDM SFP transceiver utilizes temperature-stabilized DFB (Distributed Feedback) laser technology for transmission, providing the extremely precise wavelength stability required for reliable DWDM operation with 100GHz channel spacing, paired with PIN photodiode for signal reception. The module ensures a 15 dB guaranteed optical link budget, supporting transmission distances up to 40 kilometers over standard single-mode fiber. However, distance remains an indicative parameter calculated for ease of identification – actual reach depends on minimal optical budget requirements, DWDM multiplexer insertion losses, and real-world attenuation characteristics of the installed fiber plant.
The DWDM-2.67G-SFP-40 is a hot-pluggable SFP module featuring duplex LC/UPC connectors as the optical interface. The electrical interface conforms to INF-8074i and SFP MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP host systems across multiple vendor equipment platforms. Our OC-48 DWDM SFP transceiver can be encoded for compatibility with 80+ equipment brands, enabling seamless integration into existing network infrastructure. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality, providing real-time operational parameters including transmitted and received optical power levels, module temperature, laser bias current, and supply voltage. This diagnostic data is accessible via MSA-compatible EEPROM interface, enabling comprehensive monitoring of transceiver health and performance – particularly critical in high-density DWDM environments where per-channel diagnostics facilitate rapid troubleshooting of wavelength-specific issues.
The SFP form factor, while considered a legacy standard, remains widely deployed across enterprise, carrier, and industrial networks due to its proven reliability, broad equipment support, and cost-effectiveness. The multi-rate capability from 100 Mbps to 2.67 Gbps provides exceptional operational flexibility, accommodating legacy protocol migration and mixed-speed network environments within a single transceiver platform. The module operates within a standard 0°C to 70°C commercial temperature range, with appropriate thermal considerations for sustained operation in controlled equipment room environments. Power requirements are met by a single +3.3V supply.
Standards compliance includes Gigabit Ethernet, 1G and 2G Fiber Channel, SDH/SONET OC-48/STM-16 (2.488 Gbps), OTN OTU1 (2.66 Gbps), and ITU-T G.694.1 DWDM wavelength grid conformance. The transceiver achieves multi-vendor interoperability through adherence to industry MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for full compatibility. Our OC-48 DWDM SFP transceiver is CE and RoHS certified, meeting Class 1 FDA and IEC60825-1 laser safety requirements.
Typical applications include carrier-class metro transport networks, SDH/SONET wavelength overlays, OTN edge aggregation, financial services low-latency links, and any deployment requiring maximum channel density combined with high-speed multi-rate capability. Because our focus is providing top quality service, we perform rigorous quality checks before delivery. This includes optical parameter measurements, precise wavelength verification, connector cleanliness inspection, and SFP transceiver EEPROM memory data validation tests.
